"Echandole Ganas": Latina College Students Persevering in STEM

Underrepresentation of Latina college students in science, technology, engineering, and math (STEM) remains a challenge, even though Latinx students are attending college at an increased rate. While various of the obstacles identified by them mirrored some of the issues highlighted in prior studies, the participants found ways to overcome these challenges and persevere. This qualitative study used community cultural wealth (CCW) as the theoretical framework to examine the social and academic experiences of 10 Latina college students as they navigated higher education and their STEM programs. The findings indicated that Latinas in this study leveraged a network of support to help them journey through and across contexts. This circle of support included strong relationships with friends and peers, educators, and clubs and organizations that encouraged, motivated, and inspired them. Family was also identified as a significant source of support that contributed to their aspirations towards a STEM degree and career. Additionally, spiritual, and religious connection was revealed as a source of strength that aided Latina participants’ sense of purpose to persist. Implications for higher education professionals and institutions are discussed

Teniendo en cuenta el potencial que tienen los materiales manipulativos en la enseñanza, se optó por proponer un material didáctico que, bajo un marco de referencia, permitiera hacer llegar a los estudiantes esta idea y que de esta manera se convierta en una alternativa para enseñar el tema

Energy Efficiency in Cooperative Wireless Sensor Networks

[EN] The transport of sensitive products is very important because their deterioration may cause the value lost and even the product rejection by the buyer. In addition, it is important to choose the optimal way to achieve this end. In a data network, the task of calculating the best routes is performed by routers. We can consider the optimal path as the one that provides a shortest route. However, if a real transport network is considered the shortest path can sometimes be affected by incidents and traffic jams that would make it inadvisable. On the other hand, when we need to come back, due to features that symmetry provides, it would be interesting to follow the same path in reverse sense. For this reason, in this paper we present a symmetric routing mechanism for cooperative monitoring system for the delivery of fresh products. The systems is based on a combination of fixed nodes and a mobile node that stores the path followed to be able of coming back following the same route in reverse sense. If this path is no longer available, the system will try to maintain the symmetry principle searching the route that provide the shortest time to the used in the initial trip. The paper shows the algorithm used by the systems to calculate the symmetric routes. Finally, the system is tested in a real scenario which combines different kind of roads. As the results shows, the energy consumption of this kind of nodes is highly influenced by the activity of sensors.This work has been supported by the "Ministerio de Economia y Competitividad", through the "Convocatoria 2014.

Cambio climatico y pobreza en el Ecuador

Las principales conclusiones de este trabajo son: (i) la mayor vulnerabilidad del cambio climáticopara el año 2020 probablemente se concentrará en las ciudades medianas y pequeñas de las provinciasdel Guayas, Imbabura, Santa Elena y Bolívar. En todos los años analizados, el “índice de riesgo” delGuayas es mucho mayor que otras provincias. En el caso de la población rural, el "índice provincialde riesgo al cambio climático" indica que en la década del 2020, las provincias mayormente expuestasserán Bolívar, Orellana, Los Ríos y Cañar, y (ii) el impacto del cambio climático en la salud de losecuatorianos, probablemente se concentrará en estas áreas de mayor vulnerabilidad socio-económica,y en donde las nuevas condiciones climáticas permiten la reproducción de vectores. Hay granprobabilidad de que el incremento de enfermedades epidemiológicas como la malaria y el dengue,se produzcan en zonas de mayor altitud localizada en las estribaciones del corredor Andino orientaly occidental. Es importante destacar que la definición de "vulnerabilidad socio-económica" que seutiliza para este trabajo, se relaciona con el cambio climático, en función de: (i) la exposición física alos fenómenos climáticos, (ii) la sensibilidad al cambio climático, (iii) nivel de la pobreza medida pornecesidades básicas insatisfechas, y, (iv) la debilidad en las instituciones de los gobiernos locales.Teniendo en cuenta que las variables de control de los responsables de la política pública, son lasrelacionadas a las condiciones de pobreza y de la capacidad institucional para hacer frente a laadaptación al cambio climático, la primera variable del estudio, concluye que existe una tendenciasignificativa al aumento de la dispersión geográfica de la población pobre, que es una característicapeculiar en el Ecuador, lo cual tiene fuerte influencia en el "índice de riesgo al cambio climáticoprovincial". En cuanto a la segunda variable del estudio, hace hincapié en el promedio de la debilidadde autonomía financiera, en las ciudades medianas, la cual llega a 32%, y en las pequeñas el 14,4%,en contraste con el 52,9% de las grandes ciudades (Sierra 2009), condiciones que se ven agravadaspor la mayor precariedad de los servicios públicos. En cuanto al impacto del cambio climático en la salud, la evidencia biológica ha demostrado la relaciónexistente entre la temperatura y la precipitación, variables que inciden en el incremento de la densidadde enfermedades infecciosas transmitidas por vectores, como la Malaria y el Dengue. Lacuantificación de estos efectos biológicos en los casos analizados, con el fin de modelar los probablescambios en los escenarios de clima futuro, presentan una variedad de complejidades metodológicas,agravado por la limitada disponibilidad de información. La evidencia científica indica que la malariaestá estrechamente relacionada con los cambios de las condiciones climáticas, lo cual en efecto "esun problema grave de salud pública", que demuestra la gran vulnerabilidad del país, debido a ladeficiente infraestructura básica de saneamiento y la cultura de la salud. El estudio concluye queexiste la posibilidad de que los efectos negativos del cambio climático sean atenuados si se fortalecenlos sistemas de vigilancia epidemiológica en las zonas nuevas de transición, adicionalmente, si semejoran las estrategias de comunicación y generación de incentivos (económicos y no económicos)para las prácticas de salud preventiva; y si se aumentan el suministro de infraestructura desaneamiento básico en las zonas más pobres. Para implementar esta estrategia costo-efectiva, elfortalecimiento de las capacidades institucionales de los gobiernos locales es una condición básica,así como también, instituciones locales autosuficientes son necesarias para alcanzar la efectividadde estas medidas de adaptación

Autonomous video compression system for environmental monitoring

[EN] The monitoring of natural environments is becoming a very controversial topic because people are more and more concerned about preserving and monitoring these natural spaces. The monitoring tasks are usually complemented with a network infrastructure composed by cameras and network devices that make easy the remote visualization of the monitored environments. This work presents the design, implementation and test of an autonomous video compression system for environmental monitoring. The system is based on a server in charge of collecting the videos and analyzing the network constraints. As a function of the measured parameters and the predominant color of the requested video, the system determines the best compression codec for transmitting the video through the network. Additionally, the server should run an algorithm developed in Python and MATLAB(c) in charge of analyzing the RED-GREEN-BLUE (RGB) components of the video and performing the transcoding tasks. The system has been tested with different videos and the results of Quality of Service (QoS) and Quality of Experience (QoE) shows that H264 is a good option when the predominant color of videos are black or white while XVID is one the codecs that offer interesting results when colors as red, green or blue are predominant in the video.This work has been supported by the Programa para la Formación de Personal Investigador (FPI-2015-S2-884) by the Universitat Politecnica de Valencia .

These papers are mainly focused on deployments and studies about the constraints of the underwater medium. The underwater acoustic channel is highly variable and the signal transmission can change according to environmental factors such as the temperature, pressure or salinity of the water. For this reason, it is important to know how these devices are developed and the maximum distance and data transfer rates they can achieve. To this end, this paper presents an exhaustive study of existing underwater acoustic modems where their main features are highlighted. We also review the main features of their hardware. All presented proposals in the research literature are compared with commercial underwater acoustic modems. Finally, we analyze different programs and improvements of existing network simulators that are often used to simulate and estimate the behavior of underwater networks.This work was supported by the Ministerio de Ciencia e Innovacion through the Plan Nacional de I+D+i 2008-2011 within the Subprograma de Proyectos de Investigacion Fundamental under Project TEC2011-27516.

Interactive Videos in IPTV using Hypervideo Links

[EN] One of the main advantages of Internet Protocol Television (IPTV) is the capability of full duplex communication between the Television (TV) provider and the clients which permits the interactivity of both. From this interactivity, TV providers can obtain extra information from clients. Moreover, clients can even take profit from this type of communication that allows them surfing between videos. However, this feature cannot be used in Digital Terrestrial Television (DTT). This paper shows the design and development of an interactive video for IPTV services that contains hypervideo links with additional information and content that is very useful for viewers. Furthermore, we detail the protocol used to maintain the service between the TV provider and the clients to maintain the service. Finally, the system is tested in a real scenario and the resulting measurements are provided in order to evaluate the network performance needed to offer an adequate service to each client because according to results shows, the use of hypervideo links does not imply an important increase in the ratio of packets per second.This work has been partially supported by the Postdoctoral Scholarship Contratos Postdoctorales UPV 2014 (PAID-10-14) of the Universitat Politècnica de València , by the Programa para la Formación de Personal Investigador (FPI-2015-S2-884) of the Universitat Politècnica de València .Jimenez, JM.; Lloret, J.; Abdullah, MT.; Sendra, S.

Dynamic Metric OSPF-Based Routing Protocol for Software Defined Networks

[EN] Routing protocols are needed in networking to find the optimal path to reach the destination. However, networks are changing both their use finality and their technology. Paradigms like Software Defined Networks (SDNs) introduce the possibility and the necessity to improve the routing protocols. In this paper, a modification of the Open Shortest Path First (OSPF) routing protocol is proposed in order to allow the protocol to change the metric calculation dynamically according to the network requirements. Experiments, which compare our proposal against the OSPF protocol, are performed in five different scenarios. In these scenarios, the performance of the multimedia traffic has been increased 33% in terms of bandwidth utilization, 80% of loss rate reduction and delay reduction on VoIP communications.This work has been partially supported by the "Ministerio de Educacion, Cultura y Deporte", through the "Ayudas para contratos predoctorales de Formacion del Profesorado Universitario FPU (Convocatoria 2015)".
